 * A resource loader which does nothing, except provide access to the last flex cache instance set
 * with {@link #setFlexCache}.<p>
 * 
 * The instance can be accessed via the package static variable {@link #m_flexCache}.
 * This allows unit tests in this package to do some white-box testing on the flex cache system.
